I tried it three times. Everytime the installation of centos within the vm crashes. Here are some logs: /var /log/messages: Sep 1 15:15:39 ipfire kernel: grsec: From 192.168.55.108: denied resource overstep by requesting 4096 for RLIMIT_CORE against limit 0 for /usr/bin/qemu-system-i386[qemu-system-i38:16081] uid/euid:99/99 gid/egid:1007/1007, parent /sbin/init[init:1] uid/euid:0/0 gid/egid:0/0 Sep 1 15:15:40 ipfire charon: 12[KNL] interface macvtap0 deactivated Sep 1 15:15:40 ipfire charon: 13[KNL] interface macvtap0 deleted Sep 1 15:15:40 ipfire codel: Codel AQM has been enabled on 'macvtap0'.

Hi Daniel, what did you mean you are unable to install a new VM ? Did the VM freeze or go you get a kernel panic? Could you try to boot knoppix 7.6 and post the results? I could reproduce this error and it seems that the Vm get only 50 Mb Ram assigned by libvirt. When I change the value to something normal I can boot up normal. So to me is seems that libvirt has a serious bug here and I am not happy about this. So could you try my hints and post result? Regards Jonatan
I Tried it one time again and everything work fine so, this seems this is not very good reproducible.
Hi Daniel, I tried it several times this morning but I am unable to reproduce the bug. Can you still reproduce the bug?
I have no Problem to install Centos 7. It work fine
Hi, as also Daniel Weismueller said in the chat today that it work for him now, I set this to Closed WORKSFORME. Feel free to reopen the bug, if the problem appears again. Regards Jonatan
